“Down with lame door knobs” is the motto Mary & Jeff of ModKnobs go by. They couldn’t find any suitable ones on the market when remodeling their home, so they decided to release their own line. Four styles are available — puck, matte, walnut, oak — in a handful of materials: vulcanized rubber, PaperStone (a pressed material made from recycled cardboard), and of course; walnut and oak. If you’re going for sleek and modern interior you really can’t go wrong with one of these door knobs. Prices range from $95 to $125, depending on style and material.
